TRESTLE.

Application filed June e,

rlhis invention relates to scaffolds and more particularly to a trestleemployed to support a scaffold board. 1 One object of the invention isto provide a trestle which may be adjusted longitudi- Vsame convenientlycarried from one place to another or stored in a small space.

Another object of the invention'is to provide a knock-down trestlewhich, when assembled, Will be very strong and steady.

This invention is illustrated in the accompanying drawing, Wherein-Figure 1 1s a View showing the improved trestle principally in sideelevation and partially in section;

Fig. 2 is a top plan view of the trestle;

Fig. 3 is a transverse' sectional view through the trestle;

Fig. l is an enlarged transverse sectional Vview through the bodyportion of the trestle.

The body portion of the treat-le includes a center bar or intermediatesection 1 and end sections which are connected with the center bar andadapted to be slid longitudinally thereof When it is desired toincr-ease the length of the trestle. rlhe center bar is preferablyformed of Wood although other material may be used and is rectangular incross section, as shown in Figs. 3 and 4f.. The end sections are alsopreferably formed of Wood and each includes side bars 2 disposed inparallel spaced relation to each other and retained in proper spacedrelation by blocks 3 so that they may have overlapping engage ment withthe side faces of the center bar l. The side bars may be `secured to thespacing blocks 3 by bolts, nails or other suitable fasteners e passedtransversely through them. lf' the center bar and the end ections areformed of metal, it Will be obvious that the side bars and spacing locksmay be of an integral construction or formed as sepa rate elementssuitably secured together. ln the presentillustration the center bar andthe side bars are of such length that, when the spacing blocks are inengagement with the ends of the center bar', the inner ends of the sidebars will contact, but it will be obvious that the center bar may be ofgreater 1926.

length in which case the inner ends of they side bars would at all timesbe spaced from each other.

ln order to support the body portion, there has been provit ed legs 5which may also be formed of TNood or any other suitable material and arepreferably rectangular in cross section. The companion legs at the endsof the body have their upper and lower ends beveled so that they mayhave flat engagement With the ground and side faces of the side bars 2when secured to the body in depending diverging relation to each othertransversely of the body. rllhe upper end portions of the legs arefitted into metal sockets G which are secured against the outer sidefaces of the side bars 2 by fasteners passed through their base flanges7 and securing pins 8, Which are carried by chains 9 so that they Willnot become lost, are passed through registering openings in the socketsand upper ends of 'the legs to preventthe legs `from accidentallyslipping out of the sockets. Similar pins 9 which are, of course, largerthan the pins 9 are passed through the side bars 2 and center bar 1 toprevent longitudinal movement thereof relative to each other.

ln order to firmly brace the legs and prevent them fro'm having movementlongitudinally r transversely of the body, there has been providedbraces 10 yand 11. The bracing bars 10 entend between the legs and theside bars 2 and at their ends are formed With forks adapted to straddlethe portions of the brackets 12 and 13 whichproject from the side bars 2and inner side edge faces of the legs. lotegisterine` openings are.formed in the brackets and iorks of the braces so that lsecuring pins laand 15 Which are carried by chains 16 and 17 may be passed through thebrackets and forks and firmly but removably secure the braces. The otherbraces 1,1, which prevent the legs from having movement transversely ofthe body, are also formed at their ends with forks adapted to straddleprojected portions of brackets 18 secured against theinner faces of thelegs, registering openings being formed in the brackets and forks soJthat the braces may be secured by pins 19 which are also provided withchains 20 so that they Will not be liable to become lost. t Will bereadily seen that since the braces and the legs are secured by removablepins they may be detached and the legs and braces placed longitudinallyof the body portion when storing the scaffold or carrying it from oneplace to another. It will also be obvious that the end sections of the.body portion may be either lett in engagement with the center bar ordisconnected therefrom when the scatiold is stored or transported.

Vhen the scaffold is in use, the legs are iitted into the sockets 6 andsecured by the pins 8 and the braces i0 and ll are then secured to thecooperating brackets carried by the legs and side bars. rEhe braces,when secured, "ill firmly hold the legs in proper relation to each otherand prevent them strom moving out of the desired angular relation to the'body portion. lifter the trestle has been assembled, the body portionmay be lett collapsed or it it is to support a wide scaffold board orpast-ing table, such as used by paper hangers, the end sections may bedrawn outwardly until the trestlc is ot the necessary length to extendsubstantially the -ull width `ot a table top or scat'old platform. Theend sections and intermediate section are straddled by lol-clamps 2iwhich lit snugly about the body por-tion, as shown in Figs. 3 and t, andhave their 'arms extending downwardly and terminating in threaded stemswhich project through openings in cooperating anchor strips 23 and carrysecuring nuts 2li, From an inspection of F ig. 1l, it will be readilyseen that, w-hen 'the securing nuts 2el are tightened, the U- clampstogether with their strips 23 will be drawn into tight bindingengagement with the sections lof the body and the sections will besecurely locked and prevented from sliding llong-itudinally of eachother.

if it is found that the legs 5 are not long enough to support thescaffold at the desired elevation, auxiliary legs 25 are employed.rlhese auxiliar-y YVlegs 25 are also preferably ormed of wood andrectangular in cross section and may be ot' any length desired. heyextend llong -it-udinally ot the legs 5 in overlapping relation theretoand Ipass through yokes 26 which are secured in straddling relation tothe legs 5 with their bridge portions 27 spaced from the outer faces ofthe legs. rh'e bridge portions of the yokes are formed with openings 28which are adapted to register with selected openings 2,9 formed in Ythelegs 25 and spaced troni each other longitudinally thereof so thatsecuring pins 30 may be passed through the registering openings 28 and29. One or more of the auxiliary legs could also be employed it tbetrestle is resting upon uneven ground. It the auxiliary legs .are of nogreater length than the main legs, they could be lett in engagementtherewith when not in use and secured .by the pins 30 with their lowerends spaced above the lower ends of the legs Vi but if they are etgreater length than the main legs they would, 'of course, be appliedthereto only when their use is necesser-y.

Having thus described the invention, I claim:

i. A knock-.down supportccmprising a body, sockets carried by Said bodyand extending transversely tlieretrom, companion legs having their upperends removably seated in said sockets, brackets carried :by said legsand body and having portions projeeting `thereirom and formed withopenings, braces extend-ing between said coinpanion leg-s, other bracesextending .between said legs and body, said braces being provided withll'orks straddling said brackets and formed with openings registeringwith the openings of the brackets, and removable vfasteners fitted intothe registering openings of the `brackets and braces to releasablysecure the braces.

2. A knoekvdown `trestle comprising an extensible body having endsections slidable longitudinally of each other, means to releasablysecure said end sections in a sell position, sockets carried by said endsections and extending transversely therefrom, companion legs 'havingtheir upper vends seated in said sockets, means to releasably securethe. legs inthe sockets, brackets earried by said 'legs and end Sectionsand having portions projecting 'therefrom and `formed with openings,braces extending between said companion legs, other braces ex-V tending`between said Vlegs and end sections,

said braces being provided with Aforks straddling said brackets andformed with openings registering with the openings et the brackets, andPins iitted into they gistering openings of the 'brackets and 'braces toreleasably secure the braces.

ln testimony whereof I atiix my signature.
